Nonobstetric conditions causing hypoxia during pregnancy: asthma and epilepsy

Nonobstetric medical emergencies of hypoxia may be difficult to recognize in pregnant patients whose normal physiologic condition is altered by the pregnant state. Keys to early recognition of hypoxia in pregnancy may result in appropriate medical interventions for treatment of asthma and seizures that minimize ill effects to mother and fetus. Preventive measures and patient education are important to reducing the incidence of emergencies such as status asthmaticus and status epilepticus.
